IVIETALLIC ROOFING-SHINGLE.

SPECIFICATION forming part of Letters Patent No. 246,542, dated August 30, 1881.

Application iled January 15, 1881. (No model.)

To all whom it may concern:

Beit known that I, HENRY S. N oRTHRoP, of Pittsburg, in the county ot' Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Metallic Roofing- 1Shingles, of which the following is a specificaion.

Figurel is aplan of one of my shingles. Figs. 2, 3, and 4 are sections of the same through the ribs, showing the lips and slots. Fig. 5 is an end view. Fig. 6 is a detail showing` the manner of uniting the shingles, and Fig. 7 a plan showingthemannerofplacingtheshingles on the roof.

Similar letters of reference indicate corresponding parts.

Myinvention relates to sheet-metal shingles which are to be secured to the roofs of build` ings with nails or similarfastenings, and it has for its object the construction ot' the shingles in such form that in laying them the edges may be united to forni a water-tight joint without the labor of seamin g, and the shingles fastened to the root' in such manner that the nailheads will not be exposed to the weather.

Theinvention consists in making the shingles with a rib extending along each side of the shingle, and an ornamental device in the center terminating at the upper and lower edges in short ribs, which should be the length of the lap of the shingles, and providing the two side ribs with lips at opposite ends, and one of the side ribs and one of the short ribs at the center with slots to match the tongues; also in placing nail-holes in the shingles in such relation to the tongues and slots in the ribs that the part ot the sheetneXt the tongues will be securelyfastened and thefastening will not be exposed to the weather when placed on the roof.

In the drawings, A represents a single shingle or sheet of roong formed with the side ribs, D and E, and with the short ribs B B. The center may be left lat or be ornamented with a device, c, in the center of the plate, as shown.

Near the end of one of the side ribs-say D and atthe opposite end of the other side rib, are formed the tongues a and a, preferably made by cutting a U-shaped slot in the top of the ribs or corrugations and raising the lip outward. 1

In the short rib B and the side rib, E, at the same distance from the lower end as the tongue a', are formed the slots b b. N ail-holes fand g are formed in the flange k, and the nail-holes h and/are made near the upper edge of the sheet and near the ribs B and E.

In laying the shingles the sheet F is first placed at one corner of the eave of the root' and nailed through holes fand t'. rIhe plate G is now laid, the rib E lapping over the rib D of the shingle F, with the tongue a passing through the slot b ot' the rib E. The plate G is now nailed through holes f and fi, the nail in i passing through the hole gin the iirstplatc, F. The next sheet is now to be laid and nailed as before, and so on through the rst course. The next course above is begun with a halfsheet, H, the corner of it which carries the short rib B having the slot b', being held by the tongue a of the plate F passing through the slot and being clinched down. The plate His nownailed through the holesfand t'. The nail which passes through hole falso goes through hole h of the first plate, F. The sheet I is then laid, the tongue a ot' the previous sheet passing through the slot b", and the tongue a ot' the second sheet, G, passing through the slot b of the plate I. The sheet I is then nailed through holes [and c'. It will thus be seen that the upper edge of each 4sheet is held down by nails the heads of which are covered by the lower edge of the succeeding sheet above, and that the corners covering the nails are held secure by the clinching of the tongues passing through the slot therein that the rib B of each sheet is held down by the connection of its slot b with the tongue a of the next sheet below, which is itselfl secured by the covered nail passing through the hole z'. It will also be seen that the short rib B fills the opening ot' the ribs D and E ot the sheet above, and that the rib B covers the ribs of the two sheets below.

The short ribs or the ornament, or both of them, mightbe omitted, the shinglebeing practically complete with only the side ribs; but the form shown is preferred.

Having thus fully described myinvention, I
